It will be really hard to do to make it look right and will have no benefit, not even venting the wheel arches as the plastic arch shroud will be in the way .
I will see... if I make one up - then people can pass judgement of it on the car. As we all keep saying it is often a personal thing with mods on our cars. Mine isn't by any means standard so I don't see a problem with changing things. I just love the ZS180 vents and think they'd look funky.
